Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 307,634,173, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 307,634,173 | |
| -1 | -307,634,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,634,173.
Example:
1 x 307,634,173 = 307,634,173
and
-1 x -307,634,173 = 307,634,173
Notice both answers equal 307,634,173
With that explanation out of the way, let's continue. Next, we take the number 307,634,173 and divide it by 2:
307,634,173 ÷ 2 = 153,817,086.5
If the quotient is a whole number, then 2 and 153,817,086.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 307,634,173 | |
| -1 | -307,634,173 |
Now, we try dividing 307,634,173 by 3:
307,634,173 ÷ 3 = 102,544,724.3333
If the quotient is a whole number, then 3 and 102,544,724.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 307,634,173 | |
| -1 | -307,634,173 |
Let's try dividing by 4:
307,634,173 ÷ 4 = 76,908,543.25
If the quotient is a whole number, then 4 and 76,908,543.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 307,634,173 | |
| -1 | 307,634,173 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 128,879 | 902,153 | 1,417,669 | 3,995,249 | 9,923,683 | 27,966,743 | 43,947,739 | 307,634,173 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -128,879 | -902,153 | -1,417,669 | -3,995,249 | -9,923,683 | -27,966,743 | -43,947,739 | -307,634,173 |
